# UBSan vptr blacklist.

|
# Function and type based blacklisting use a mangled name, and it is especially
|
|
# tricky to represent C++ types. For now, any possible changes by name manglings
|
|
# are simply represented as wildcard expressions of regexp, and thus it might be
|
|
# over-blacklisted.

# If base and derived classes have identifical memory layouts (i.e., the same

# object size) and both have no virtual functions, we blacklist them as there
|
|
